OXIS International, Inc. Receives $1 Million Up-Front Payment from Licensing Deal with Synvista Therapeutics

FOSTER CITY, Calif.--(BUSINESS WIRE)--Oxis International Inc. (OTCBB: OXIS - News), a biopharmaceutical company focused on commercializing predictive biomarkers, clinical assays and nutraceutical and therapeutic products, announced today that the Company has received $500,000 in funding, which was the initial payment due under the license agreement with Synvista Therapeutics, Inc. (AMEX: SYI - News) for BXT- 51072 (ALT 2074). This license agreement was initially announced on April 9, 2007 and the licensing fee was to be paid following the closing of a Synvista financing approved by the Synvista shareholders. Synvista Therapeutics was formerly known as Alteon, Inc.

Under the terms of the license agreement, Synvista had to initially pay Oxis $500,000 and invest $500,000 in Oxis common stock, at a per share price equal to 125% of the quoted price of Oxis’ common stock immediately prior to the date of the investment, and no less than $0.24 per share. Oxis’ stock closed yesterday at $0.13 per share. Oxis is also entitled to receive development milestones payments as well as royalties from the sales of products developed from the license.

“The outlicensing of BXT 51072 from our antioxidant drug portfolio represents a significant opportunity for Oxis,” stated Marvin S. Hausman MD, Pres./CEO of Oxis International. “The one million dollars received represents non-dilutive financing for our Company and reflects the potential for BXT 51072. We look forward to working with Synvista on the development of this promising product.”

“Approximately 200,000 diabetics with the haptoglobin 2/2 genetic marker will experience a heart attack each year and there are more than 7 million diabetics who carry this marker in the United States alone,” said Noah Berkowitz, MD, Ph.D., CEO of Synvista Therapeutics.

“ALT -2074 (BXT- 51072), is a new molecular entity and a new therapeutic treatment strategy. The potential size of the market for the prevention of cardiovascular events in diabetics carrying this genetic biomarker could range from $600 million to more than $2 billion.”

ALT-2074 (BXT 51072) is a glutathione peroxidase mimetic in clinical development for reducing the morbidity and mortality of patients with diabetes following a myocardial infarction. ALT-2074 has demonstrated potential efficacy in animal models of heart attack and in a 20-patient clinical trial in ulcerative colitis. Synvista’s goal is to develop ALT-2074 in acute coronary syndrome as a targeted drug for high risk diabetic patients. The compound has demonstrated the ability to reduce infarct size by approximately 85 percent in a mouse model of heart attack called ischemia reperfusion injury. It is currently being evaluated in a clinical trial for evidence of myocardial protection following angioplasty in high-risk diabetic patients. This Phase 2 clinical study was opened for enrollment in Israel, in May 2006. Synvista expects to report interim results of this trial later in 2007. In June 2007, the company initiated a Phase 2 study using ALT-2074 in diabetic patients, testing positive for a marker of increased cardiovascular risk (haptoglobin genotype testing). Patients are being treated with ascending doses of ALT-2074 or placebo for 28 days as we track inflammatory biomarkers and functional improvement in their reverse cholesterol transport. Results from this study are anticipated in the first quarter of 2008.
